"Swimming Pool" uploaded to stock.xchng by getwired.
Summer 2008 officially begins today, June 20, at 7:50 EDT (at least in the Northern Hemisphere). Here at Distillations, we’re celebrating with a show dedicated to poolside lounging. We’ve got the sunscreen and the chlorine—in fact, two different kinds of chlorine. Later in the show, CHF’ s own David Caruso explains how buoyancy allows some people to float and makes others sink. So lather up, stoke the grill, and enjoy the solstice. Element of the Week: Titanium.
